One of his advisers told Britain’s Daily Telegraph on Tuesday that Romney is better positioned than President Obama to foster a strong relationship with the U.K. because of his "Anglo-Saxon" connection to the country. "We are part of an Anglo-Saxon heritage, and he feels the relationship is special," the unnamed aide said of Romney. "The White House didn’t fully appreciate the shared history we have."

The accusation that President Obama doesn’t appreciate America’s “Anglo-Saxon heritage” is a barely veiled racist attack against the president, not to mention the millions of Americans who are not descended from ancient Britons. Newt Gingrich was getting at the same thing when he accused the president of having a “Kenyan, anti-colonial” worldview. Mike Huckabee was too when he said Obama grew up near “madrassas” rather than “going to Boy Scout meetings.”

Unsurprisingly, the Romney campaign is now denying that the words were ever said (though they won’t specify by whom they were not said, nor have they asked for a retraction). I hope they’re telling the truth: the comment was massively offensive, and shouldn’t be coming from anywhere near a major political campaign. But the Romney campaign’s denials aren’t really letting the candidate off the hook. That sort of comment calls for a strong rebuke, not just a tepid denial.

But I’m not holding my breath. After all, when another Romney surrogate, former George H.W. Bush chief of staff John Sununu said the president needs to "learn how to be an American" – another appeal to the popular right-wing idea that the president is some sort of foreign imposter – Sununu attempted to walk back his own comment, but the campaign was silent.

As it happens, Romney is in a similar situation with another of his foreign policy advisers, former Bush administration official John Bolton who went on anti-Muslim activist Frank Gaffney’s radio show yesterday to defend Rep. Michele Bachmann’s attacks on Muslim-Americans working for the U.S. government. Bolton’s comments set him apart from prominent Republicans including John McCain and John Boehner, who have rebuked Bachmann’s witch hunt. Yet Romney, who apparently will be only appearing for photo ops in London tomorrow, hasn’t said a word.
